Application April 16,

4` Claims.

This invention relates to extension or oiset hinges which are especially adapted for hanging windows, doors, and the like.

One of the important objects of this invention is the production of a simple and efficient hinge which will facilitate the swinging outwardly of the window or door supported thereby, in a manner whereby the window or door may be swung beyond the frame or may be reversed for the purpose of facilitating the washing, painting, and the like, of the outside face of the window, door, sash or panel.

A further object of this invention is the production of a simple and efficient hinge for supporting a window sash and the like, in such a manner as to permit the maximum amount of air and light to enter through a window and also to permit the positioning of a sash in a manner to prevent a direct draft from passing through a window.

Other objects and advantages will appear throughout the following specication and claims.

Figure 15 is a sectional perspective View of one corner of a sash and panel, showing a further modified type of hinge mounting;

Figure 16 is a perspective View of a sash and panel showing a still further modied form of hinge structure;

Figure 17 is a perspective view of a sash and panel, showing the panel swung to an open position;

Figure 18 is a perspective View of a sash and panel showing the same as applied to a casement window By referring to the drawings, it will be seen that A designates the window frame in which frame A are slidably mounted the sashes I0 and i El in the conventional manner, a suitable latching means l2 being employed for locking the sashes together. Each sash supports panels I3 and I4 which t within the openings I of the sashes. These panels i3 and I4 may be held in a closed position by means of suitable latches I6. Weather strips i'I may also extend over the adjoining `edges of the panels I3 and I4 and the sashesA Ii) and II to constitute a seal therefor, if desired, the weather strips I'I being notched, as at I8, near their respective ends to permit the supporting hinges, hereinafter described, for the panels i3 and Ill to operate.

Each panel I3 and I4 is supported by a pair of specially constructed hinges designated generally by the letter B, and these hinges are similarly constructed. Each hinge B comprises an elongated anchoring plate I9 which is preferably inset within a socket 2S of the rail of the sash upon which the hinge is mounted, the plate I9 of the upper sash being inset to extend flush with the under side of the upper rail of the sash and the plate i9 of the lower hinge being inset to extend iiush with the upper face of the lower rail of the sash, as clearly illustrated in Figure 3. The plate I9 in each instance is suitably anchored upon the sash by means of suitable screws 2l which are countersunk, as shown.

An extension arm 22 is pivotally secured, as at 23, to one face of the anchoring plate I9 by means of a counter-sunk rivet, the extension plate or arm 22 of the upper hinge being secured to the under face of the anchoring plate I9 and the extension arm or plate 22 of the lower hinge being secured to the upper face of the anchoring plate i9, as shown in Figure 3. A pintle pin 24 is secured to the extension arm 22 at one end, as shown clearly in Figure 10, the pin being riveted or otherwise secured to the arm 22 and being adapted to receive the barrel of the hinge plate 25, which hinge plate 25 is secured in any suitable manner to one edge of one of the panels I3 or I4. The hinge plate 25 is preferably fitted within the recesses formed in the side edges of the panels I3 and I4' which abut the sides of the sashes I il and II. 'Ihe pintle pins 24 are preferably provided with suitable heads for holding the barrel portions of the hinge plates 25 upon the pintle pins 24.

Each extension arm or plate 22 is provided with a substantially U-shaped notch 21 which is adapted to receive a tongue 28 of the clutch plate 29, which clutch plate 29 is slidably mounted upon the anchoring plate I9, in the manner as shown in Figure 10, and in a position to cause the tongue 28 to register with and t into the U. shaped notch 21. The clutch plate 29 is secured to the anchoring plate I9 by means of a screw 39 which extends through an elongated slot 3| formed in the clutch plate 29, the head of the screw 36 being counter-sunk to extend iiush with the plate 29.

In mounting the hinge, the sash I3, such as is shown in Figure 3, is provided with a socket 32 upon its upper and lower faces of the thickness of the clutch plate 29 and extension arm 22 in a manner to allow the hinge to be folded in a position to cause the edge of the hinge to extend flush with the outer face of the supporting panel when the hinge is in a closed position such as is shown in Figure 5. The notch 3| is of sufcient length to allow the clutch plate 29 to be moved ,to and from a locking position. All of the hinges are similarly constructed in the forms shown in Figures l to 1l, inclusive, and when mounted upon the respective panels of the respective sashes the pintle pin 24 of the upper hinge extends downwardly and the pintle pin 24 of the lower hinge extends upwardly, as is clearly shown in Figures 1 and 3. It should be understood that both the upper and lower hinges are similarly constructed, but only their positions are reversed.

By carefully considering Figures 4, 5 and 6, the operation of the device will be clearly understood. The panel I3 for example, may be swung outwardly with respect to the sash I 9 upon the pintle pins 24 of the hinges B, if it is merely desired to swing the panels to an open position at right angles to the sash I0. If it is desired, however, to throw the panel I3 to a position where it will lie back over the frame A, the clutch plate 29 may be moved to the position shown in Figure 6, drawing the tongue 28 out of the notch 21 and allcwing the extension plate or arm 22 to pivot upon its pivot 23 and move to a position at right angles to the anchoring plate I9, moving the sash i3 in spaced relation with respect to the frame A and to a position substantially parallel to the sash I0, as is shown in Figure 6. By means of this particular type of hinge, it will be seen that the panels I3 and I4 may be swung open to a position at substantially right angles to the sash i?! or by releasing the clutching plate 29 the sashes may be swung to a position substantially parallel to the supporting sash or to a position as shown in Figure 6. As is clearly shown in Figure 8, when the panel, such for instance as the panel I3, is in a closed position upon the sash I0, the hinge will be completely shielded or housed between the panel and the sash and the moving parts are so positioned as to extend ush with the abutting faces of the panels and sash allowing the panels and sash to snugly t with respect to each other. Where weather stripping, such as is shown in Figures 1, 2 and 3, is used, it is important that the inner edge of the stripping be in line with the center of the pintle pin so that the sash may be swung open suiciently to allow the clutch plate to be'operated and lowering the same.

for the purpose of throwing the sash to a position such as is shown in Figure 6.

From the foregoing description it will be seen that a very simple and eicient means has been provided for supporting the hinged panels I3 and I4 upon the sashes I and II so as to allow the sashes to Vslide over each other when raising It should be further understood that the clutching plate 29 will rigidly lock the extension arm 22 in position until the clutching plate is released so that the device will act as a conventional hinge while the clutching plate 29 is in a locking position and will act as an extension hinge when the clutching plate is released to an unlockingl position such as is shown in Figure 6. y

In Figure 12 there is shown a modied type of the invention wherein a sash 32a is illustrated carrying a panel 33. An anchoring plate 34 is secured to one face of the sash 35 by means of the lugs or ears 35, the plate 34 extending laterally at substantially right angles to the outer face of the sash 32a. An extension plate 31 is pivotally secured, as at 38, to the upper face of the plate 34 and carries a pintle pin 39 which engages a hinge plate 40 secured to the outer face of the panel 33, as shown in Figure 12. The extension plate 31 is provided with a notch 4I for receiving the tongue 42 of the slidably mounted clutch plate 43 which clutch plate 43 is slidably mounted upon the anchoring plate 34, as shown in Figure 12. The hinge shown in Figure 12 operates in a manner similarY to that as shown in Figures 1 to 11 inclusive, with the exception that the structure shown in Figure l2 is secured to one face of the sash 32at and panel 33 and is not counter-sunk or inset as is the case with the previously described form.

In Figures 13 and 14, I have shown a further modified form of the invention, wherein 44 indi- Cates the sash which is provided with a weather strip 45, notched as at 46. A panel 41 is mounted within the sash 44 and is notched, as at 48, for receiving the hinge plate 49, which hinge plate 49 is engaged by a pintle pin 50 carried by the outer Yend of a pivoted link 5I, which pivoted link 5I is pivoted, as at 52, to the anchoring plate 53. The anchoring plate 53 is inset within the socket 54 formed in the sash 44, and the link 5I is inset within a socket 55 formed in the abutting face of the panel 41. In the form shown in Figures 13 and 14, the extension arm 5I is pivoted to the anchoring plate 53 and no clutching ldevice is provided, the extension arm 5I being free to allow the panel 41 to swing outwardly and away from the side of the sash 44, as the panel 41 is swung'outwardly.

In Figure 15 there is shown a further modified form of my invention, wherein 56 indicates a sash which carries a panel 51. An anchoring plate 58 is secured to the inner face of the sash 56 and extends at right angles thereto. The panel 51 carries a hinge plate 59 which engages a pintle pin 60 carried by the outer end of the extension plate 6I, which extension plate 6I is pivotally secured, as at 62, to the anchoring plate 58, as shown in Figure 15. The inner end of the extension plate or arm 6I is notched, as at 63, and is adapted to be' engaged by the tongue 64 of the sliding clutch plate which is similar to the clutch plate 29 previously described. The an# choring plate 58 in the form shown in Figure 15 is preferably counter-sunk or inset within the sash 56 so as to extend flush therewith and to allow the panel 51 to fit snugly in position when closed.

As shown in Figure 16 and Figure 17, there is illustrated a further modified form of the invention. In this form a sash is illustrated which supports a panel 1I, the panel 1l carrying hinge plates 12 at its upper and lower inner corners, which hinge plates 12 are pivotally connected to the outer ends of the extension links 13, which links 13 are pivoted, as at 14, to the inner face of the sash 10 at a point approximately the center thereof. The panel 1l is preferably notched, as at 15, upon its upper and lower faces to allow the extension links or arms 13 to snugly t between the panel 1| and the sash 10. In the form shown in Figure 17, it will be seen that the panel 1I may be swung to the position shown in full lines in Figure 17 at substantially right angles to the sash 10, or may be swung to either of the two dotted positions, allowing free and easy access to either the inner or the outer faces of the panel 1l for the purpose of washing the glass plane, or painting or cleaning the panel.

In Figure 18 there is shown a still further modified form of the invention as applied to a casement window, wherein a sash 16 is illustrated in which is mounted a panel 11 which is pivotally connected at its upper and lower inner corners to the outer ends of the upper and lower links 18 and 19 respectively. Each link 18 and 19 is in turn pivotally connected at its inner end to a suitable bracket 80 secured to the inner face of the sash 16 near its center, in this way allowing the panel 11 to be swung to a position substantially at right angles to the sash 16 or to an offset position substantially parallel to the sash 16, either to the right or to the left, as shown in dotted lines in Figure 18.

From the foregoing description it will be seen that a very simple and efficient extension hinge is provided which will lie close to or be shielded within the frame and panel structure, and at the same time allow the panel to be swung to and from an open position, as well as to and from an extended position. This will allow the panel to be adjusted for the convenient washing and cleaning thereof from the inside of a building and without the necessity of reaching out through the window frame and it should be further understood that since the panel may be swung to a variety of adjusted positions, the panel or panels may be adjusted to deect draft and to prevent the entrance of a direct draft through the window by reflecting the draft, in this way providing a Ventilating means with a minimum amount of draft. It will also be seen that a simple and eicient clutching means has been provided whereby the hinge may be either used as a conventional hinge support, or by means of a slight adjustment the hinge may provide an extension hinge support to permit the supported panel to be swung to an offset position with respect to its supporting sash. The present type of hinge and particularly that type shown in Figures 1 to 14 inclusive, is especially adapted for use in conjunction with types of windows such as illustrated in Figure 1 wherein swinging panels are carried by vertically slidable sashes, this hinge structure holding the panels in a position whereby the sashes may freely slide one over the other at the same time allowing the panels to be freely swung and bodily moved inwardly with respect to the supporting frame when the sashes are properly adjusted to permit of such movement.
